Yes, many subarctic cultures, particularly those in regions like the northern parts of Canada and Alaska, used to construct homes that involved digging into the ground. One notable type of dwelling used by some Indigenous peoples in these regions is called a "dugout" or "earth lodge."
These structures were often partially underground, providing insulation from the extreme cold conditions typical of subarctic environments. The dugouts were made by excavating a pit and then constructing a roof with materials such as wood and sod, which helped to keep the interior warm.
Additionally, some groups, such as the Chukchi and other Siberian Indigenous peoples, used similar techniques for building shelters suited to their climate. Overall, these structures demonstrated a deep understanding of the environment and the resources available to these cultures.
